DIY Foil Stream

After more than 6 weeks in quarantine, my kids started to get bored. It was time to try something new. I saw online this foil stream DIY project and thought I give it a try.

The weather got warmer, and everyone enjoys playing with water, this must be a win I thought and was right! My kids loved this easy craft idea and had a blast.

They were able to help me set things up and played the whole afternoon with it. The foil even lasted us for several more days. Of course, it depends on how careful your kids are with it!

Another bonus point is that it’s a quite cheap but fun craft for the kids. Just make sure to put on some water cloth or be aware that their cloth might get wet.

Follow these simple steps to get build your own backyard foil stream:

Step 1: Prepare the foil

Layout the heavy-duty foil on the ground. Preferably on a little hill so the water can flow downwards.

Step 2: Build sides

Fold the foil up by about 5cm/2,5 inches on both sides. Those are your walls and prevent the water from flowing over and keeps it going in the right direction.

Step 3: Stabilize the foil

Press down on the foil and secure the stream with rocks, little sticks, or other materials you can find in your garden. Go for a material hunt prior to this step. This way the foil does not blow away while hunting for objects.

Step 4: Build a dam

Go and get some extra stones in your garden. Use them to build a dam somewhere along the stream.

Step 5: Have fun

Get a bucket or watering can full of water, splash it on your foil river, and have a good time. Maybe you can even build a little raft or paper boat prior to your water project and let it run down your finished stream!

  • If you have a garden with foil or grass, this will be definitely a better place to build your fun activity. Never the less concrete also works. The benefit of grass or foil is that it is easier to secure the foil. Simply push it down into the ground, so it does not move around for better construction.
  • On windy days you might need more than one person to build the stream. Just include your children in this easy DIY process. They will love being mommy’s little or big helpers.
  • Put a bucket at the end of the foil to collect and reuse the water. This way you do not waste water, save money, and gives the kids an extra roll to keep them occupied.
  • This water play is more indented for big kids. My toddler wanted to step on it the whole time and managed to make wholes into the foil that way. It cost me a lot of afford and energy to prevent him from doing it over and over again!

Overall my kids really enjoyed this outdoor activity. We got to spend the whole afternoon outside and really enjoy this cool refreshing summer project.

It’s a quick set-up and the few materials can be found in your home or garden, which is always a bonus point for me.

Also, should older children be able to build the stream by themselves.
